How to Get Free Iron in Empires & Puzzles

Empires & Puzzles (Small Giant Games, part of the Zynga group) mixes match-3 combat with empire management: you build structures, train heroes, and fight turn-based battles using boards of colored gems. All of that requires two very different resources. On one hand there are Gems, the game's premium currency, used to summon heroes through the various portals; they can be bought, but are also earned for free (albeit in limited amounts) by completing the adventure map, missions, and some events. On the other hand there's Iron, the resource that really drives your day-to-day progress: without it you can't level up your Stronghold, build or upgrade structures, or train troops at the Training Camp. Unlike Gems, Iron is 100% free and earned by playing: in every battle on the adventure map, in events, in daily missions, and in alliance wars. In this guide, using real data from the community and the game's wiki, we explain the most profitable ways to get Iron without spending a cent, which stages to farm, and how much you can expect to accumulate per month depending on your play pace.

What's the fastest way to get Iron in Empires & Puzzles?

We've gathered and verified every real method for getting free Iron, ranked from most to least profitable based on the time they take and what you can actually earn from each. No tricks, no generators — just the game's own mechanics.

Up to ~1,900 Iron per energy point on the best known stage (15-4) Daily

Farm the adventure map stages with the best Iron ratio

The main source of Iron is replaying old Season 1 stages once you've completed them, using your World Energy, which regenerates over time. The community has identified stages with a very good Iron-per-energy ratio, such as 15-4, 12-1, 10-5, 8-4, and 6-8. You don't need to progress through the story to farm these stages: you can repeat them as many times as you like. Combine it with extra energy Flags, which recharge over time or can be bought with Gems if you have some to spare, to maximize your daily farming runs.

Reduced energy cost and increased loot across all Atlantis stages Variable

Take advantage of Atlantis Rises

Atlantis Rises is a recurring event (roughly every three weeks, lasting several days) during which every stage of the Atlantis Season costs less energy and gives better rewards, including Iron. These days are when it's most worthwhile to spend your energy and extra flags, so it's worth saving energy refills (flasks) to use exactly when the event is active instead of on regular days.

Chest with Iron, Food, and Recruits on completing each mission Daily

Daily Wanted Missions

Every day, Wanted Mission chests appear at your Stronghold asking you to defeat a set number of enemies of a specific color in normal, titan, or raid battles. They complete almost effortlessly, since they count enemies you kill during your regular play, and their reward includes Iron along with Food, Recruits, and occasionally battle items. It's the most 'passive' way to add Iron, since it doesn't require playing any extra.

Weekly war chest with Iron and Food depending on the alliance's result Weekly

Alliance War and war chest

If your alliance takes part in Alliance Wars, every valid attack contributes to a collective chest that's handed out when the war ends, with Iron, Food, and other materials depending on the team's performance. Alliance Quests also give out chests with resources just for participating, even if your alliance doesn't win. Joining an active alliance that regularly participates multiplies this source at no extra cost.

Chest every 8 raid wins, with variable Iron, Food, or Gems Variable

Raid chests

Every eight wins in Raids (asynchronous PvP battles against other players' defenses) opens a chest with a random reward that can include Iron, Food, battle items, or more rarely, Gems. It's not the most reliable source since it depends on your win streak, but since you're playing raids to climb the Trophy League anyway, the Iron comes as an extra bonus at no additional effort.

Doesn't generate new Iron, only raises the accumulation cap One-time

Expand Iron Storage

Unlike other management games, Empires & Puzzles has no mines or farms that passively produce Iron over time: all Iron is earned by playing. Iron Storage buildings only serve to raise the maximum you can accumulate, preventing the surplus from being lost when you're above the cap after a good farming session. It's worth leveling them up as soon as you can, especially ahead of events like Atlantis Rises, so you don't waste loot.

How much free Iron can you get per month?

Source	Estimated amount	Frequency
Farming adventure map stages	Variable (depends on available energy and stage level)	Daily
Wanted Missions	Variable, small-to-medium chests	Daily
Alliance War / Alliance Quests	Variable depending on participation and result	Weekly
Atlantis Rises (increased loot)	Extra multiplier on top of regular farming	Roughly every 3 weeks
Raid chests	Variable, depends on PvP wins	Variable
Estimated total	Not quantifiable with a reliable figure	—

The amount of Iron depends directly on the player's maximum energy level, the number of extra flags, whether it coincides with Atlantis Rises, and the exact stage being farmed, so giving a single monthly figure would be misleading; what matters is prioritizing the best-ratio stages and not wasting energy on regular days.

Frequently asked questions

Can you buy Iron directly with real money in Empires & Puzzles?

There's no direct purchase of Iron with real money. You can speed up earning it by buying Gems and using them for extra energy flags or energy refills, which in turn let you farm more stages and get more Iron — but always through playing battles, never as a direct resource purchase.

Is it worth farming Iron on old Season 1 stages instead of progressing through the story?

Yes, for pure farming it's worth repeating already-completed stages with a good Iron-per-energy ratio (like 15-4, 12-1, or 8-4), since they pay out more for the same cost than advancing through new, high-difficulty stages. Progress through the main story to unlock content, but save your leftover energy for the known farming stages.

Are websites promising unlimited free Gem or Iron generators safe to use?

No, any website, app, or video promising an unlimited Gem or Iron generator is a scam. Empires & Puzzles has no official way to generate resources outside the game itself, and these kinds of sites are designed to steal your account credentials or get you to complete fraudulent surveys. The only legitimate way to get Iron is by playing, and the only way to get free Gems is through the adventure map, missions, videos, and official events within the game itself.
